Patent DE-3827271-A1 (DE)
Title: Motorised aircraft passenger staircase
IPC: B64F1/315
Filed: 1988-08-11
Abstract: The previously known motorised aircraft passenger staircases had to be driven up to the aircraft fuselage from the driver's cab of the carrier vehicle, which required an extremely high level of attention and could be carried out only with difficulty in large aircraft. According to the invention, it is proposed for the upper platform and/or the entire aircraft passenger staircase to be mounted on the carrier vehicle such that it can be moved along the longitudinal axis of said carrier vehicle and, in this case, for this movement to be controlled from the upper platform of the aircraft passenger staircase so that this operator is in the immediate vicinity of the contact between the aircraft passenger staircase and the aircraft fuselage.

Abstract: A step selector for a stepped transformer has an electrically insulating cylindrical wall provided with fixed contacts, e.g. at different levels and, for each contact level, a radial arm composed wholly of electrically insulating material is affixed to a cylindrical shaft rotatable about the axis of the cylinder and within the latter. The radial arm has a flange lying against the shaft and extending over substantially 120 DEG  of an arc thereof. An inward projection on the flange engages a recess in the shaft and the flange is held against the shaft by at least one band of fibrous material impregnated with a self-hardening synthetic resin. The outer end of the arm carries a contact bridge slidable on a contact ring which nonrotatably surrounds the shaft and lies in the plane of the respective fixed contact which is engageable by the bridge.

Patent DE-3841504-A1 (DE)
Title: Butchers tube appliances with stuffing device
Inventor: KRETZER ADOLF
IPC: A47J43/16
Filed: 1988-12-09
Abstract: Up to now, butchers have painstakingly hollowed out pieces of meat using knives, in order to be able to fill the meat with other edible contents. Injection bags are normally used during filling. Use of the tubes, which are sharpened at their front apertures and should, at least in their front section, be made of steel or a light metal, makes it possible to penetrate pieces of meat by exertion of a slight pressure and to hollow out the said pieces of meat by pulling out or rotating the piece of meat pressed into the tube together with the said tube. The stuffing device can be used to press different edible contents into the hollowed-out piece of meat through the tubes. As the tubes may be of different sizes, there is a multiplicity of possible applications. It may, for example, be expedient to remove pieces of meat from larger pieces of meat by means of insertion or rotation for a particular application (tournedos). Cleaning and handling of the tubes together with the stuffing device is much easier than it is when injection bags are used.
Patent DE-3842349-A1 (DE)
Title: Non self-priming liquid pump having a bleeding (venting) stage
Inventor: SZETELI ANDREAS
IPC: F04D9/04
Filed: 1988-12-16
Abstract: The invention relates to a non self-priming liquid pump. The centrifugal pumps, e.g., belong to this category. Since before it is started up the pump system always has air in it, such pumps must be bled before being started up. The bleeding is performed using a positive displacement pump which cooperates with the centrifugal pump. In this case, use is made of a sliding vane (vane-type) rotary pump or the like, which is arranged in a rotationally fixed fashion on the drive shaft of the centrifugal pump. When the feed (delivery) pump is started up, the sliding vane pump initially sucks the air from the pump system until the delivery liquid reaches the centrifugal pump. Thereafter, the centrifugal pump takes over the delivery of the liquid. In order to shut down (switch off) the sliding vane rotary pump in this working state, a channel is provided from the suction region of the centrifugal pump to the interior region of the sliding vane rotary pump. The underpressure in the interior region of the sliding vane pump which forms in the suction region propagates via this channel and as a result the rotary slide vane is drawn into the rotor of the sliding vane rotary pump. <IMAGE>

Abstract: An electrical device for preparing hot instant drinks comprises a water container 2 arranged in a housing at such a height that a hot water outlet 11 arranged at the base 13 thereof is located above a brewing container 5 or a space 100 receiving same. Heated water from the water container 2 is delivered via a valve (14, 14') located at the hot water outlet 11, the valve (14, 14') being opened by a controller 18 as soon as a temperature sensor (15, 20) determines that the water in the water container 2 has reached the desired temperature. The water in container 2 is heated by circulating it through tubes 8, 9, the portion 8' of which is in contact with the hot plate 3, until the desired temperature is reached. <IMAGE>
Patent DE-3903410-A1 (DE)
Title: Liquid soot filter
Inventor: STARK HELMUT
IPC: B01D47/02
Filed: 1989-02-06
Abstract: According to the invention, soot is filtered off from exhaust gases by introducing the exhaust gases into a liquid bath, preferably water, by means of the apparatus for a fine distribution of gas in liquids of File No. P3902486.5 or another distribution apparatus. As a result the soot is bound in the liquid and separated from the exhaust gases and is no longer able to escape into the air and contribute to its contamination. This liquid soot filter is installed directly downstream of the exhaust gas generator, upstream of any downstream exhaust gas scrubber binding the exhaust gases with chemicals. As a result mutual contamination and mixing of soot and salts produced in the exhaust gas neutralisation are avoided. As a result both can be reused without mutual contamination.
